Our free and fast tool will convert most 3D mesh or GLTF (Graphics Language Transmission Format) model files to a standard DAE (COLLADA - Collaborative Design Activity) file that can then be edited further in most popular 3D editing packages such as Blender or 3D printed without any further processing. Our conversion tool can also batch convert multiple GLTF files; up to 25 files at a time can be converted.
To convert your GLTF file, click the Upload button above and select the file to convert. Once selected, the file will be converted to a DAE file and will be ready for download shortly afterwards. For more information about the GLTF to DAE conversion process, see the conversion information section below.

The GLTF file format, which can also have the GLB file extension depending on whether the content is binary or text, JSON is a 3D file format used to describe 3D worlds and, as such, contains geometric data such as vertices, faces, normals, animations, and other 3D scene-related data.
The format, described by its creators as the "JPEG of 3D", has gained in popularity and is supported by a wide range of 3D modeling applications such as Blender and MeshLab. The GLTF format is an open standard that is maintained by the Khronos Group.

The DAE format (also known as COLLADA) is a 3D file format used to describe 3D models, meshes, and 3D worlds using a simple text-based structure. The format was introduced in 2004 by Sony Computer Entertainment and is currently managed by the Khronos Group.
DAE files are a text/XML-based file format containing 3D geometric information used to describe 3D objects and meshes such as vertices, faces, animations, materials, camera/lighting elements, and other related metadata. The format has widespread usage and support, with applications such as Blender and MeshLab being able to read and write to it.
Our tool will save any texture files separately; these additional files will be included with your final DAE file at the time of download.
Converting from the GLTF file format to DAE can be a complex process, and any tool used for this conversion process needs to be able to handle a variety of data conversion tasks as well as identify any defects within the 3D model and fix them. Here we will explain the conversion process used by our tool to accurately convert your GLTF file to a valid DAE 3D model. Let's start with the conversion process, which involves the following steps:
In its simplest form, an GLTF file is a binary data file containing 3D data such as vertices, faces, normals, and more. When combined, these make up the 3D model you see on your screen.
When our tool reads this 3D data, all we are interested in are the vertices, faces, normals, materials, and textures, as this is the only data that can be accurately converted into the final DAE file.
The GLTF file can contain data such as material definitions and textures that describe how a particular set of 3D geometry should be rendered. As we are creating an DAE file, which supports both materials and textures, our tool will attempt to load any materials and textures present in the GLTF file.
For more information regarding the GLTF file format, please see this great article that goes into a lot of detail explaining the GLTF format.
With the GLTF file data read, our tool generates an internal representation of the full 3D model and will attempt to fix any geometry issues encountered. Along with repairing any issues with the 3D model, the tool will remove any duplicated vertices and prepare the model for exporting to the DAE format.
With the conversion process entering its final stages, our tool now needs to take the in-memory 3D model we have created in step 2 and convert it to the DAE format.
Along with the completed DAE file, any textures that were present in the original GLTF file will be saved in either PNG or JPG format, depending on the original image format. If the original format was neither of these, for example, if your model contained a texture in the TGA format, it will be converted to a PNG.
Yes! If your GLTF file contains textured geometry, the texture image files along with the texture coordinates (UV data) will be exported with the final DAE file.
We aim to process all GLTF to DAE conversions as quickly as possible, this usually takes around 5 seconds but can be more for larger more complex files so please be patient.
We aim to create the most accurate conversions with our tools. Our tools are under constant development with new features and improvements being added every week.
Yes, of course! We do not store the GLTF file you submit to us. The resulting DAE file, once created is deleted 15 minutes after upload and the download link will expire after this time.
No. All our conversion tools process your GLTF file on our dedicated conversion servers, meaning you can use our tools on low-spec computers, laptops, tablets, and mobile devices and receive your converted DAE file quickly.
Yes! Our GLTF to DAE tool will run on any system with a modern web browser. No specialist software is needed to run any of our conversion tools.
Yes. Although you can use an Ad Blocker, if you like our GLTF conversion tool please consider white-listing our site. When an Ad Blocker is enabled there are some conversion limits on some of our tools and processing/conversion times will be longer.
Yes. When you have converted your GLTF to DAE, there is a "Feedback" option that you can use to let us know of any issues you encountered when converting your file.
